Buggy code:
public abstract class AbstractSolrIngest implements SolrIngest { public Metadata metadata ; public SolrClient solrClient ; protected final Logger logger = LoggerFactory . getLogger ( this . getClass ( ) ) ; public enum MetadataElement { Title , Abstract , LayerName , Publisher , Originator , Bounds , ThemeKeywords , PlaceKeywords , Access , LayerId , WorkspaceName , Location , Institution , FullText , DataType , Georeferenced , ContentDate ; } Set < AbstractSolrIngest .

Fix:
return name ;
